There is nothing new under the sun: the history of the photo editing is almost as old as photography itself. Spirit photography was first widely employed by William H. Mumler in the 1860s, but the earliest pieces were made by Sir David Brewster for his 1856 book The Stereoscope: Its History, Theory, and Construction. Even though he was using the simple double exposure technique and was revealed as a fraud, some other spirit photographers came up in the next decades. Here are some of the most interesting pieces of spirit photography before Photoshop.
